Heading Description Example Entry
ID Unique number for the entry. 3
Name The data that identifies the family (population) or the clone by a number and/or name. WN185.01
Alternative Another name that is commonly used with the clone or the family.
Family If the entry is a population then the seed lot number is shown. If the entry is a clone, the family number is shown, if known.
Family comments
Sex M (Male), F (Female), U (Unknown), or B (Both) U
Genus/Material Type PC (Populus Clone), PF (Populus Family), SC (Salix Clone), SF (Salix Family), PO (Pollen) PC
Source Type BR (Bred), OP (Open Pollinated), SC (Selected Cutting) or SC-OP (Selected Cutting from an OP family), WS/WC (Wild Seed/Wild Cutting), or NA (Not Available/Not Applicable) NA
Category PPN (Pure Poplar species - Native), PPNN (Pure Poplar species - Non-Native), HP (Hybrid Poplar), HPN? (Hybrid Poplar Native - putative), HA (Hybrid Aspen), NH (New Hybrid >1998) (seedlots only), W (Willow), PWN (Pure Willow Native), CD86 (1986 register). HP
Female parent The species name(s) of the female parent, for example: deltoides. Parentheses are used to distinguish between parents in three-species clones. maximowiczii
Female parent clone The name(s) and/or number of the female that was used to produce the clone, for example: alba (A69) × tremula (E12), ‘alba’ is entered in the Female Parent field and ‘A69’ in the  Female Parent Clone field.  Parentheses are used to distinguish between parents in three-species clones.  QB-77592
Male parent The species name(s) of the male parent, for example: tremula.  Parentheses are used to distinguish between parents in three-species clones. deltoides
Male parent clone The name(s) and/or number of the male that was used to produce the clone, for example: ‘tremula’ is entered in the Male Parent field and ‘E12’ in the Male Parent Clone field.  If a putative parent is known but not verified, a question mark is added after the species (e.g.: nigra?).  Parentheses are used to distinguish between parents in three-species clones. SBC-M01-07
Year bred The year that breeding or collection took place - a 4 digit number, for example: 1980, or NA (Not Available/Not Applicable). 2001
Year selected The year the material was selected (4-digits) or NA (Not Available/Not Applicable). 2003
Year released The year the material was released for commercial use (4-digits) or NA (Not Available/Not Applicable). NA
Hybrid designation Throughout the development of this database, it became clear that there are a number of Latinized names, all preceded with '×', commonly used in naming hybrids (e.g. balsamifera × deltoides is known as ×jackii). The hybrid designation is included to improve the search capability of the database. There is one caveat, however: there may be many examples, particularly with the 1986 data, where the exact hybrid lineage has not been scientifically verified, so please use this only as a search tool, unless the designation has been appropriately confirmed. All cultivar names are capitalized.
Tested Y (Yes) or N (No) or U (Unknown) N
Current Status Indicates if the clone is in a trial, Y (Yes), or N (No) Y
Source Location The geographic location where the material was obtained from. Indian Head, Saskatchewan
Contact The name of the organization that is responsible for the administration of the material, e.g.: AAFC-PFRA Shelterbelt Centre. AAFC-PFRA Shelterbelt Centre
Commercial Y (Yes) or N (No) field to indicate if the clone is a current commercial clone. N
